Ok so I have a Google account for an organization. But when I have that account logged in on my phone some of the security restrictions impact all accounts on my phone. I have a pixel 7a with Android 16 if it matters.

I would love to have access to this gmail account, with notifications, on my phone without forwarding the emails to one of my personal accounts. Any way to do that within the Gmail app itself, or if I need a different app, any recommendations?

In my perfect world I'd have OneDrive access too, but I can use a browser window there if needed.

So I am attempting to swap phones, but because I am trying to use a pixel 9 xl and it was not previously on my network, I have to wait 40 days to unlock it so I can install GrapheneOS.
I saw on Monday that suddenly there were a lot of photos dated from last Sunday on the phone's default "Photo" app. I have been keeping things to a minimum: I haven't logged into anything Google, and I've only installed F-Droid apps. Also, I had some issues with my desktop and did a clean reinstall 2 weeks ago.

But still disturbingly, my ENTIRE ~/Picture directory (and subdirectories) from my PC were loaded onto my phone.

Now, I'd like to clarify, I do have a few Google accounts, but I have them logged into my desktop with containers on Firefox (particularly, I use one for a current hobby type situation that I have to use, and the other is a 20+ account that I've moved away from, but I still want to monitor).

I want to find out why anything from my PC ended up on this somewhat secluded phone. I have not attached it via USB, and while I have been attempting to limit my connections, I do need to access some of my rl/PC stuff on the phone. But I haven't logged into a google account on it, yet, all my photos showed up on it. I have not plugged it into the computer since I tried putting GrapheneOS on it, which failed due to it not being unlocked (PLEASE CORRECT ME IF I'M WRONG HERE, BECAUSE I STILL HAVE TO WAIT 2 WEEKS!), yet all these pictures that I would have never expected ended up on this phone.

And I just was looking around my ~/ directory, and I saw a directory titled .nuget... I checked pacman (I'm on Arch, so that's my package manager), and it's not installed, but I deleted it because it had a lot of sketch files that ... okay, so I deleted the directory and honestly I don't have it anymore to state what exactly was in it. But I'm really tired and it triggered issues, and I looked and I see that nuget is not installed... so okay, I'm just gonna end this here because I do need to go to bed.

But, would anyone be able to provide any assistance/advice/suggestions on how the heck my phone magically obtained my Linux desktop Picture files?
